VMWare Ubuntu time sync for Amazon EMR

EMR requires time sync for the ruby scripts to work.

1) make a symlink to /etc/init.d/ntpdate if the program is in /etc/default or the symlink isn't there or it is in a different location. Probably best to not go copying executables around the file system.

training@training-vm:/etc$ sudo ln -s /etc/default/ntpdate /etc/init.d/ntpdate

2) run the time sync update on powerup
training@training-vm:/etc$ sudo update-rc.d ntpdate defaults
